How Long Will A Super Capacitor Booster Pack hold a charge?

In terms of lifespan,the good life expectancy of a capacitor jump starter is the following. Capacitor jump starters generally have a longer life than traditional lead-acid battery jump starters, which can withstand more charge and discharge cycles, and have a longer service life. With over 10,000 charge cycles compared to 300-500 for lead-acid batteries, supercapacitor jump starters offer 10x longer service life and superior durability.

Consider the math: an active rider who uses their jump starter 20 times per season across both winter (snowmobile) and summer (ATV) activities would get 250+ years of service from a quality supercapacitor jump starter, versus just 7-12 years from a traditional battery jump starter. Even accounting for occasional emergency use and maintenance charging, the supercapacitor technology delivers 10-15 times longer service life.

Which is better for your fleet team: a battery jump starter pack?

Fleet mechanics need equipment that works every time, and traditional battery maintenance creates unnecessary operational challenges. Fleet maintenance requires keeping jump starters at full charge, especially during extreme cold when power is most challenged. Battery-based units often fail precisely when needed most, during winter emergencies or after extended storage periods. Long-Term Fleet Economics

Fleet maintenance with supercapacitor jump starters can serve for decades rather than requiring replacement every few years. This dramatically reduces equipment replacement costs and inventory management complexity. Fleet managers can invest once in reliable supercapacitor technology instead of continuously replacing degraded battery units.

Mangkurt Typhoon Hit the Southeast Area of China

Yesterday the most powerful typhoon crashed down the Southeast Area of China on September 17^th, 2018. All people witnessed that the typhoon “Chebi” ruined down the whole Japan and Hurricane Florence horrify 1500,000 people to escape from the disaster area. However, tropical storm Mangkurt is more devastating than Chebi and Florence, so you can image how terrifying it is!

Before storm typhoon was coming, the government and citizen has taken action to reduce the loss and injury as less as possible.  The government command all companies to stop working, all schools to stop lessons ,all factories stop manufacturing, all metros, bus, airplane stop running and all people should better stay in house.

At the same time, the government ask all rescue team to prepare for rescue operation to help people out of danger.

All citizens also did their best to reduce their property loss and life injuries. They went to supermarket to storage enough food to spend those hard days, use bricks to rise up their cars and plastic bag to wrap their cars to avoid to be drowned, strength their housing doors and windows.

                

However, some area has no power due to the typhoon, if no fan or air condition, it is too hot to take it in the summer. If we have a portable power station in emergency, we can use it to charge fan, rice cooker, smart phone,ect. So no worry to be of in hunger and in the darkness to spend the hard days.

Today Mangkurt has moving from Shenzhen, and all be back to the normal, people go to work, students go to school, the metro, bus , and airplane start to in operation. But the streets are all in mess and disorder after heavy storm. Many trees fall down and block the road, some area are in floods, some buildings are collapsed down.This Mangkurt bring a great disaster to shenzhen, but we know much more about natural disaster and know how to face it when it happens.
